Modern QR codes that remain easy to scan
Choose a content template instead of manually assembling special URI formats. The generator creates standards-based email, SMS, phone, location, calendar, contact, Wi-Fi, WhatsApp, and UPI payloads, then renders them entirely on this device.
Design for reliability first
Strong contrast and a four-module quiet zone matter more than decoration. Logos work best with High error correction and excavation enabled. A QR preview is not proof of scanability, so test the final downloaded asset at its real print size and on multiple phones.
Use the right export
PNG is the safest general-purpose choice, WebP is compact for modern websites, and SVG is the best option for professional print and design workflows. Transparent backgrounds can be useful in artwork, but verify that the final surface still provides strong contrast.
